Intel Arc B580 vs NVIDIA Rubin GPU Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc B580 and the NVIDIA Rubin GPU. The head-to-head comparison table is empty, and the recorded win counts for both products are zero. This absence is itself informative: the two products operate in entirely separate performance tiers and use cases, so no common benchmark suite has produced comparable scores.

The Intel Arc B580 has a complete benchmark profile. Its 3DMark Steel Nomad DX12 score is 3068. In Geekbench, it records 92,821 in OpenCL and 109,672 in Vulkan. Passmark results include 15,748 in G3D, 7,729 in GPU Compute, 709 in G2D, and legacy DirectX scores of 183 (DX9), 128 (DX11), and 76 each for DX10 and DX12. The average benchmark score across all recorded tests is 23,021.

The NVIDIA Rubin GPU has no recorded benchmarks. Its average benchmark score is zero, and its percentile ranking among all GPUs is 50, which reflects the absence of measured data rather than actual performance. The database assigns this neutral percentile because there are no test results to analyze.

The Intel Arc B580's nearest rivals in the database are instructive for positioning. The AMD Radeon RX 580 2048SP averages 23,061, which is 0.2% higher than the Arc B580. The NVIDIA GeForce RTX 2080 averages 22,895, putting the Arc B580 0.6% ahead. The NVIDIA GeForce RTX 3080 averages 23,172, making the Arc B580 0.7% behind. The NVIDIA P106-100 averages 23,249, placing the Arc B580 1% behind. These deltas are all within roughly one percentage point, indicating that the Arc B580 sits in a tightly clustered performance band around the 23,000 average score mark.

The NVIDIA Rubin GPU has no nearest rivals listed. With no benchmark data, the database cannot establish any competitive relationships for it. The Intel product's position is clear from the numbers, while the NVIDIA product's position remains undefined.

Where Each One Wins

The Intel Arc B580 wins in every measurable benchmark category because it is the only product with recorded test results. The data shows 10 distinct benchmark entries for the Arc B580, covering DirectX 9 through DirectX 12, OpenCL, Vulkan, G2D, G3D, and compute workloads. Each score contributes to its 68th percentile ranking among all GPUs, which places it above the median but below the top tier.

The NVIDIA Rubin GPU wins in architectural scale and memory capacity, though these are specification advantages rather than benchmark victories. Its 288 GB HBM4 memory and 22.1 TB/s bandwidth dwarf the Arc B580's 12 GB GDDR6 and 456.0 GB/s. The Rubin GPU's FP32 throughput of 130.0 TFLOPS exceeds the Arc B580's 13.67 TFLOPS by a factor of nearly ten. Texture rate on the Rubin GPU is 2,031.2 GTexel/s versus 427.2 GTexel/s on the Arc B580.

Use case separation is stark. The Arc B580 is a graphics card with display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1) and DirectX 12 Ultimate support, suited to client-side rendering workloads. The Rubin GPU has no display outputs and lists DirectX, OpenGL, and Vulkan as N/A, indicating it targets server-side compute rather than interactive graphics. The Arc B580's 190 W TDP and dual-slot form factor contrast with the Rubin GPU's 2300 W TDP and SXM module design, confirming different deployment environments.

Specification Differences

The two products differ across nearly every specification field. The Arc B580 uses the BMG-G21 chip on a 5 nm TSMC process, while the Rubin GPU uses the GR100 chip on a 3 nm TSMC process. Transistor counts are 19,600 million for the Arc B580 versus 336,000 million for the Rubin GPU. Die size measures 272 mm² for the Arc B580 and 1456 mm² for the Rubin GPU. Transistor density is 72.1M per mm² versus 230.8M per mm².

Memory subsystems are completely different. The Arc B580 has 12 GB GDDR6 with a 192-bit bus and 456.0 GB/s bandwidth. The Rubin GPU has 288 GB HBM4 with a 16384-bit bus and 22.1 TB/s bandwidth. Memory clocks are 2375 MHz (19 Gbps effective) for the Arc B580 and 2695 MHz (10.8 Gbps effective) for the Rubin GPU.

Compute resources differ substantially. The Arc B580 has 2560 shading units, 160 TMUs, 80 ROPs, and 20 RT cores. The Rubin GPU has 28,672 shading units, 896 TMUs, 24 ROPs, and 896 tensor cores. The Arc B580 lists no tensor cores, while the Rubin GPU lists no RT cores. Pixel rates are 213.6 GPixel/s for the Arc B580 and 54.41 GPixel/s for the Rubin GPU, an unusual inversion where the smaller card has the higher pixel rate.

Power and physical specifications diverge widely. The Arc B580 has a 190 W TDP with a 450 W suggested PSU and uses a single 8-pin power connector. The Rubin GPU has a 2300 W TDP with a 2700 W suggested PSU and no listed power connectors, consistent with its SXM module form factor. The Arc B580 is dual-slot with dimensions of 272 mm length, 115 mm height, and 45 mm width. The Rubin GPU has no recorded dimensions.

Bus interfaces differ by generation. The Arc B580 uses PCIe 4.0 x8, while the Rubin GPU uses PCIe 6.0 x16. Display outputs are present only on the Arc B580, which offers 1x HDMI 2.1a and 3x DisplayPort 2.1. The Rubin GPU has no outputs. API support is limited to the Arc B580, which lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Rubin GPU lists N/A for all three APIs.

Architecture Differences

The Arc B580 uses the Xe2-HPG architecture, part of the Battlemage generation (Arc 5). Its predecessor is Alchemist. The Rubin GPU uses the Rubin architecture, part of the Server Rubin (Rxx) generation, with Server Blackwell as its predecessor. These are fundamentally different design lineages: one is a client graphics architecture, the other is a server compute architecture.

The Arc B580's Xe2-HPG design includes dedicated RT cores (20 of them) and relies on 5 nm process technology from TSMC. The transistor density of 72.1M per mm² reflects a relatively spacious layout. The Rubin GPU's GR100 chip packs 230.8M transistors per mm² on 3 nm TSMC, indicating a much denser design. The Rubin architecture includes 896 tensor cores, which the Arc B580 lacks, and omits RT cores, which the Arc B580 includes.

Memory architecture reveals the divergent purposes. The Arc B580's 192-bit bus with GDDR6 is a conventional client GPU design. The Rubin GPU's 16384-bit bus with HBM4 is a server-class memory system designed for massive bandwidth. The 22.1 TB/s bandwidth of the Rubin GPU is over 48 times the Arc B580's 456.0 GB/s.

The API support difference reflects the target workloads. The Arc B580 supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it suitable for gaming and general graphics applications. The Rubin GPU lists no API support, indicating it is not designed for interactive graphics but for compute tasks that bypass traditional graphics APIs. The presence of tensor cores on the Rubin GPU and their absence on the Arc B580 further confirms the compute focus.

The Verdict

The data presents a clear division of purpose. The Intel Arc B580 is a client graphics card with measurable benchmark performance, a 68th percentile ranking among all GPUs, and a launch MSRP of 249 USD. Its benchmark profile shows it competing within one percentage point of established mid-range to upper-mid-range cards like the RTX 2080 and RTX 3080. The 3DMark Steel Nomad score of 3068 and Geekbench Vulkan score of 109,672 provide concrete reference points for its graphics capabilities.

The NVIDIA Rubin GPU is a server-class compute accelerator with no benchmark data. Its 130.0 TFLOPS FP32 throughput, 288 GB HBM4 memory, and 22.1 TB/s bandwidth indicate extreme compute capacity, but the database contains no measurements to verify real-world performance. The absence of display outputs and API support confirms it is not meant for graphics workloads.

For users seeking a graphics card with verified performance data, the Arc B580 is the only choice with recorded benchmarks. Its performance cluster around the 23,000 average score places it in a competitive position. For users requiring massive compute throughput and memory capacity in a server context, the Rubin GPU's specifications point to far higher capacity, but no benchmark evidence exists to quantify its advantage.

The database record is asymmetric: one product is fully characterized with measurements, the other is characterized only by specifications. The verdict follows the data. The Arc B580 is the benchmarked option for graphics workloads. The Rubin GPU is the specified option for server compute, with its performance potential remaining unmeasured.
